| I just bought a 2007 TSX(automatic) less than three weeks ago. We have gone thru 2 1/2 tanks of gas in only 675 miles. Does this sound like a computer error that need adjusted. The driving has been more freeway than city driving. Premium gas has been put in every time. Any help would be appreciated and the dealer is having a service techician call me tommrrow. | |

Divided by 675 miles gives you 20 to 23 MPG. Not unreasonable for a brand-new car driven in mixed conditions during break-in. Keep an eye on it and look for an improvement after break-in. |

Replying to: osubuck31 (Feb 20, 2007 5:46 pm) I get 22-23 MPG in the winter and 24-25 MPG in the summer with most of the miles being open city roads or congested freeway. I track mileage on every tank of gas and the first tank after I bought the car is still the worst I've seen. The mileage definitely gets a little better as the engine breaks in.

Replying to: osubuck31 (Feb 20, 2007 5:46 pm) I took a trip from Albuquerque to Denver (and back) and I averaged 29 mpg with an average speed of 81 mph. I thought was pretty good because the lowest elevation was 5280 ft (Denver) and the highest was +7500 feet at Raton Pass. I had the occasional run of 90-95 mph between Colorado Springs/Denver. The TSX is an excellent car to travel in at +80 mph. |

we drove from the east side of NC to the west side and back. Our average speed was 77mph and we averaged almost 34mpg. we drove thru cherokee to tenn.(the smokey mountains)

| Just did a round trip from Vancouver, WA to Seattle. Stayed a few MPH above posted speeds (e.g. 70 = 73, 60 = 63). I averaged 36 MPG for the trip of over 300 miles. It is a 2006 TSX, automatic with 11,500 miles registerd. Just an FYI. | |

Replying to: nj2pa2nc (Mar 05, 2007 3:38 am)  and we had a great time! We even saw 2bear cubs at the S.M.N.P.! We stayed in Gatlinburg and we went by coach bus! The bus drivers flew!! We did a normally 16hour drive (S. Miami to Gatlinburg) in 12hours up and in 9hours (Atlanta to Miami usually 13hours) back while stopping at rest stops and one walmart on the return trip. Anywho... Did you record the RPMS on the TSX by any chance? The TSX tac needle is usually high so I'm surprised you got the almost 34mpg. Any particular tips?

Replying to: nj2pa2nc (May 06, 2007 4:22 pm) Anywho, again, The TSX desperately needs a 6th gear with automatic and a higher final drive ratio if it cruises at 3.6krpm. My accord(95 v6) is around 3.4krpm with a 4speed auto at 80mph! Honda definitely needs to get to it with the trannys larger(6-8speed) transmissions. I hope the TL's rpm at 80mph isn't that high. My next car is likely to be a Acura TSX, TL, or MDX between the 2004 and 2006(07 for TSX & TL) model years. I'm sure if the TSX had a 6th gear or higher final drive, it would cruise at 80mph at 2.3krpm. That should translate to maybe 36mpg highway. Not to mention the TSX(accord euro) diesel that gets 42mpg in other parts of the world. I'm still holding off for it  ... -Cj |
